The fiangee 16 are formed with outwardly pressed portlons or corrugationsfll which "extend frorh theinner'ertgesef'the fienges 16 towar'cl 'the outer "edges of the flanges, "16. The corrugetlone 2-1 are forrhetl to produce recesses 1n the mner feces of the flange'sflG end said recesses preferably tl'e'crezisefin Widtlm 'din' depth ffonftheir:i'un'er ende 'toward therouterfectges otth'e flanges 16"a'nd ere-"afl'zipted te ipertiehy receive end. teem gage with the usual transverse gripping lugs on the tread surface of the tire 2 so thatcircumferential slipping of the armor on the tire 2 in service will be positively prevented.

The inner supporting ring 1 fits snugly between the plates 9 and the lines of juncture of the plates 9 with the flanges 16 and the rings 1 and the flanges 16 thus conjointly form an annular socket or seat for the reception of the approximately outer half portion of the pneumatic tire 2. The inner edge portions of the flanges 16 may be reinforced by forming the flanges 16 with rolled or beaded inner edge portions 17 in which circumferentially extending reinforcing wires 18 are imbedded.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The armor is applied to a pneumatic tire when the tire is deflated and the approximately outer half or tread portion ,of the tire will be disposed between the flanges 16 within the inner supporting ring 1 of the armor. 'Whcn the tire ispinflated, it will be expanded againstthe flanges 16 and against the supporting ring 1 of the armor. The friction between the pneumatic tire casing and the walls of the flanges l6and the supporting ring 1 of the armor and the engagementof the outwardly pressed or corrugated portions 21"0f the flanges 16 with the gripping lugs on the tire casing will prevent circumferential slipping of the armor on the tire casing and will assure the retention of the armor firmly in place on the pneumatictire casing. The

pneumatic tire thus will be well protected against puncture and against accidental injury and the wheel will still be resiliently supported in substantially the same manner as thoughthe armor were omitted. The plates 9 of the armor may be provided at intervals with openings 19 and the flanges 6 may have openings 20 in alignment with the openings 19, thus permitting ventilation of the space within the armor outwardly of the supporting ring 1 and between the flanges 6. The solid tire 14 may be replaced when required at a relatively slight cost.

Obviously, the invention is susceptible of embodiment in forms other than. that which is illustrated in the accompanying drawings, and I therefore consider as my own all such modifications and adaptations thereof as fairly fall within the scope of the appended claims. a

I claim 1 i y 1. An armor for pneumatic tires comprising an inner supporting member including a.

ring adapted to fit on the periphery of a pneumatic tire and a pair of substantially parallel flanges extending radially outward from the edges of said ring, a pair of plates of disk formation straddling said flanges and having oppositely flaring flanges at ported on the outer edges of said first named flanges, and a solid tire fitting on said outer supporting ring between the outer edge portions of said platesand extending outwardly beyond the outer edges of said plates, said side plates and said first named flanges having aligned ventilating openings.

2. An armor for pneumatic t1rescomprising an inner supporting ring adapted to fit on the periphery of a pneumatic tire, a pair of side plates clampedagainst the edges of said supporting ring and having a pair of oppositely flaring flanges at their inner ed es adapted to embrace the tread portion 0 a pneumatic tire, and means received between said side plates for supporting an additional tire between the outer edge portions of said plates, said flaring flanges, having depressions in their inner faces for partially receiving and engaging wit-braised portions of the tread of said pneumatic tire.

3. An armor for pneumatic tires comprising an inner supporting ring adapted to fit on the periphery of a pneumatic tire, a pair of side plates clamped against the edges of said supporting ring and having a pair of oppositely flaring flanges at their inner edges adapted to embrace the tread portion of a pneumatic tire, and means received between said side plates for supporting an additional tire between the outer edge portions of said plates, said. flaring flanges having depressions in their inner faces for partially re. ceiving and engaging with raised portions of the tread of said pneumatic tire, said depressions extending from the inner edges of said flaring flanges toward the outer edges of said flanges, said depressions decreasing in width and depth from their inner ends toward their outer ends. r

4t. An armor for pneumatic tires coinpris ing an inner supporting ring adapted to fit on the periphery of a pneumatic tire, a pair of side plates clamped against the edges of said supporting ring and having a pair of oppositely flaring flanges at their inner edges adapted to embrace the tread, portion of a pneumatic tire, and means receivedbetween said side plates for supporting an additional tire between the outer edge portions of said 1 plates, said flanges at the inner edges of said plates being concavo-convex in cross sec-i tional configuration with the convexly curved faces thereof turned outward, saidflflanges having corrugated portions for engaging with the usuallugs or protuberances on the tread of said pneumatic tire.

5. An armor for pneumatic tires comprising an inner supporting ring adapted to fit on the periphery of a pneumatic tire, a pair of side plates clamped against the edges of said supporting ring and having a pair of oppositely flaring flanges at their inneredges adapted to embrace the tread portion of a pneumatic tire, and means received between said side plates for supporting an additional tire between the outer edge portions of said plates, said flanges at the inner edges of said plates being concave-convex in cross sectional configuration with the convexly curved faces thereof turned outward, said flanges having corrugated portions for engaging With the usual lugs or protuberances on the tread of said pneumatic tire, said corrugated portions extending from the inner edges of said flanges toward the outer edges of the flanges and serving 'to produce depressions in the inner faces of said flanges, said depressions being adapted to partially receive and to engage with the usual lugs on the tread of the tire.
